LPub3D is an Open Source WYSIWYG editing application for creating LEGO® style digital building instructions producing PDF, PNG, JPG and BMP formatted content. It uses the LDraw parts library and reads the LDraw DAT, LDR and MPD model file formats.

LPub3D supports standard and high definition part libraries and do not require the LDraw library to be preinstalled. Archive (.zip) packages for both official and unofficial parts are bundled with LPub3D. Follow the linked image below to acquire the LGEO part library.

LDraw LDraw-Logo LDraw™ (LDraw.org) parts is an open standard library that allow users to create virtual models and scenes. Three LDraw part libraries are bundled with LPub3D.
LEGO LDraw.org official and unofficial LEGO® part library.

VEXIQ VEX IQ® unofficial LDraw library created by Philippe Hurbain (Philo).
